As disclosed in the accompanying (rawings, 1* denotes a substantially horizontally disposed main frame including the side beams 1 connected by the transverse beams 2 and the transverse beams 2 are connected by the substantially centrally located longitudinally directed beams 3. The rear portions of the side beams 1 and the intermediate beams have rotatably engz d therewith the supporting elements 4-. herein disclosed as rollers. he forward portion of the frame F is supported by the element or roller 5 positioned at substantially the transverse center of the frame and of a length to substantially bridge the space between the elements or rollers a so that the machine may be employed with facility in rolling the ground.

The roller 5 is supported by a yoke 6 suitably secured to the lower end portion of an upstanding spindle 7. The spindle "i" is retatably engaged with the forward transverse beam 2 and has atlixed to its upper end portion an arcuate worm rack or segment 8 engaged by a worm 9. The worm 9 is fixed to a rearwardly extending steering shaft 10 supported by suitable bearings 11 and is provided at its rear end portion with an operating wheel 12 so that the direction of travel of the machine may be readily controlled Carried by a side beam 1 in close proximity to the longitudinal center thereof is a vertically disposed bearing 14 through which is loosely directed a vertically extending threaded shank 15 and engaged with the upper portion of the shank 15 a worm member 1'6 whereby rotation of said worm member 16 in one direction imparts upward movement to the shank 15. In mesh with the worm member 16 is a worm 17 carried by the inwardly and rearwardly directed shaft 18 supported by suitable bearings 19. The inner end portion of the shaft 18 is provided with an operating wheel 20 so that the shaft 18 may be properly rotated to effect the desired raising or lowering of the shank 15.

The lower end portion of the shank 15 is operatively connected as at 21 with an upstanding member 22 carried by the plow or earth working member 23. The plow or member 23 has also engaged therewith a forwardly directed beam 2 1 operatively engaged as at '25 with the lower end portion of a vertically disposed shank 26. The shank 2G is disposed through a bearing 27 carried by the adjacent side beam 1. Engaged with the upper portion of the shank 26 and coacting with the bearing 27 is a worm member 23 in mesh with a wornr29. The worm 29 is carried by a rearwardly and inwardly inclined shaft 30 supported by the bearings 31 and is provided at its inner end with an operating wheel 32 whereby the shaft 30 may be rotated. By rotating the worm member 28 the shank 26 may be raised or lowered to control the depth of penetrationof the plow or ground working member 23, while said plow or member 23 maybe readily raised to an inoperative position upon the requisite rotation of the shank 15.

Suitably secured as at with the sheath of the beam 24- is a forwardly directed draw bar 3 1. The forward end portion of the bar 3 1 is pivotally engaged. as at 35 with the forward end portion of the adjacent beam 1.

The plow or ground working member 23 as herein employed is provided with a mold board a or the like whereby the earth or other material loosened by the plow or earth working member is thrown upon the lower portion of the transversely directed and upwardly inclined elevating mechanism E.

The lifting mechanism E includes an endless carrier 36 traveling between the side boards 37. The upper end portion of the elevator E is pivotally supported by the upstanding posts 37 carried by the side beam 1 of the frame F whereby the lower portion is capable of vertical swinging movement so that the same may be raised or lowered into working position. The side boards 37 of the elevator E at a desired point intermediate their length have engaged therewith the lower extremities of the flexible members 38 which will engage with the drums 39 carried by the shaft 40. The shaft 10 is suitably positioned above the elevator E and is supported by the standards or posts 410 carried by the frame F, and particularly one of the beams 3. The shaft 4E0 is provided with a worm wheel 41 in mesh with a worm 42 carried by a suitable shaft 13. The shaft is adapted to be operated in any preferred manner so that desired rotation may be imparted to the shaft 10 for raising or lowering the lower end portion of the elevator E. l n Figs. 2 and 3 the driving means for the shaft is diagrammatically disclosed. The elevator belt is composed of L shape bars of steel and malleable chain attachments.

15 denotes a drive shaft suitably support ed by the intermediate beams 3 and in driven connection in a well known manner with internal gears carried by the rollers 4. The driven shaft'is operatively connected with a driving shaft 416 in operative connection with a suitable motor M indicated by dotted lines in Fig. 2. This motor is preferably of the internal combustion tvpe although I do not wish to be understood as limiting myself in this respect. The upper roller or drum of the elevator E over which the carrier 36- passes. has its shaft 17 operatively connected with a shaft 48 in driven connection with the shaft 16' as is believed to be clearly illustrated in l ig. 1 of the accomg'ianying lrawings. By this means it will be obvious that requisite travel may be imposed to the carrier 36 from the motor M.

Each of the beams 1 is of an I type and clamped as at 19 to the forward endpoi'tion of said beam is a k-hannel beam 50 arranged inwardly thereof and whereby a guidew'ay 51 is provided for the sliding channel beam ltotatably supported by the beams 50 is a transversely disposed shaft 53 having its opposite end portions extending within the guideways 51 and each end portion of the shaft within a guideway 51 has fixed thereto a gear 54. One gear 5 1 meshes with a rack 55 carried by the lower flange of the coact' ing beam 52 while the second gear 50 coacts with a rack 55 carried by the upper flange of the coacting beam 52. The central por tion of the shaft 53 has fixed thereto a worm wheel 56 meshing with a worm 57. The worm 57 is fixed to a rearwardly directed shaft provided at its rear extremity with an operating wheel 59 whereby desired rotation may be imparted to the shaft As the shaft is rotated, one of the beams 52 will be extended and the other retrazcted.

The forward end portion of each of the beams 52 has loosely directed therethrough a vertically disposed rod (30 and in threaded engagement with the upper portion of the rod (30 and contacting with the upper flange of the beam 52 is a worm member (31. in mesh with a worm 62. The worm 62 is suitably fixed to a shaft 63 xtending rearwardly and longitudinally of the adjacent beam 1. The forward end portion of the shaft 63 is rotatably-supported by the bearing 64: carried by the beam 52 and the opposite end portion of the shaft is loosely directed through the bearings (35 carried by the adjacent beam 1. lrlounted upon the shaft 63 between the bearings 65 for rotation with said shaft is a gear 66. The shaft 63 has free endwise movement through the gear 66 so that desired compensation will be had for the endwise adjustment of the beam 52.

Secured as at 67 to the lower end portion of the rod or shank 60 is a vertically disposed rigid a1 '1 68 having its lower end portion secured as at (35) to a block or shoe 7 The block or shoe 70 is provided with a pair of rearwardly directed and vertically spaced ears 71 between which is secured as at 72 the forward end portion of a bracing rod 73. The rod 73' extends upwardly and rearwardly and has its rear end portion secured as at 74 to the adjacent side beam 1.

The blocks 70 are adapted to have secured thereto the end portions of a scraper S as indirated by dotted lines in Fig. l and said scraper can be adjusted at a desired incline transversely of the machine by desired relative adjustment of the beams one with respect to the other. This scraper S may be of any desired construction and is adapted to engage the road surface or other work to facilitate the grading thereof.

The opposite end portions of the plow A are also adapted to be securedto the block or shoe 70 and said plow A is preferably V- shaped in top plan with its apex forwardly directed and of a vertical cross sectional configuration as particularly illustrated in Fig. 5. The lower portion of the plow A prefer ably comprises a removable member 7 This meinoer 75 has contact with the road or other surface and by having the same removable it can be readily replaced should the same llGt'OIHQ unduly worn. I also find it of advantage to connect the plow A through the medium of the loop or yoke 76 carried thereby w'th the arm 68 and through which yoke or loop 76 said arm is directed as is particularly illustrated in Fig. 9.

I also find it of advantage to provide each end portion of the plow A with a rearwardly directed extension or abutment 7? adapted to engage the outer end the adjacent beam 52 so that the finict-ioning of the plow A is a ssurcd.

In Fig. 13 of the accompanying drawings ll disclose a modified mounting for the vertirally dispos d rods or shanks hereinbefore erred to a d wherein the rod or shank 26 is loosely directed through a beam 1 and has threaded thereuipon at a. point between the vertically spaced flanges of the beam 1 a worm member 25 meshing with a worm 29 carried by a shaft 30. In order to effect this mounting it is to be understood that the beam l is provided with the requisite openings. In this form of my invention it is also of advantage to incase the worm member 28" and the worm 29 in the housing or casing 77.

The rods or shanks GO operate to raise or lower the blocks or shoes 70 as the occasions of practice may require and this is accomand is provided at its rear end portion with an operating wheel 79.

When the plow A is in use it is also of advantage to provide means for supporting uac ape portion thereof and in order to provide for this support the front portion of the frame is provided with a forwardly directed bracket 79 having loosely disposed through the outer end portion thereof a rod or shank 80 having its lower end portion suitably engaged with the apex portion of the plow A. The upper end portion of the rod or shank 80 has threaded thereon a worm. member 81 engaging the upper face of the bracket 79 and in mesh with a worm 82 carried by the rearwardly directed shaft 83. The shaft 83 as illustrated in Fig. 1 conrr rises plurality of articulated sections and the rear end portion of said shaft 83 is provided with an operating wheel 84 whereby the requisite rotation may be imparted to the shaft 83 to raise or lower the shank or rod 80 as the occasions of practice may necessitate.

From the foregoing description, it is thought to be obvious that a road working machine constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that ll l) my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
